This was mostly concerned about SM PS mode so that's what I'm asking. I
don't actually know what that is anyway though, hence the question. We
keep adding API in mac80211 and nobody really knows when to call it.
Maybe you should (maybe team up with Atheros for it) write a "HT
hardware with mac80211" chapter in the documentation?
